Abstract
An integrated waste management facility for a well installation comprises a separator for separating oily water produced by a well installation into oil and water, means for cleaning waste water and / or sanitary waste, destructive means for destroying other waste materials, and means for controlling the facility in an integrated manner.
Description
Waste ManaEelnent Facility_for Well Installations This invention
relates to an integrated waste management facility for well installations, for example hydrocarbon extraction well installations.
The construction and operation of a well installation results in substantial quantities of waste products, not just from the process of fluid extraction, but also from the human involvement in the process. Such waste products are extremely diverse. Apart from the usual waste products resulting from human activity in any other process, such as sanitary, food and clinical, a well installation involves additional waste products specific to that process, such as oily water from oil I water separators. Currently, such waste disposal is implemented in a somewhat haphazard way, by the employment of various pieces of equipment supplied by a variety of manufacturers, with little or no co-ordination between the processes.
Waste disposal from well installations have to meet the current standards which are set on an international level by the International Maritime Organisation (1MO) and documented in MARPOL 73/78. However, in order to explore the remaining world stocks of oil it is increasingly necessary to operate in areas that are very environmentally sensitive, In such areas, the industry will not only have to work with nature and public opinion to enable operation, but often, for example in Alaska, Florida, and the Great Barrier Reef, comply with local legislation that currently far exceeds the current international legislation. Increasingly stringent discharge quality legislation, both marine and land based, is beginning to cause significant changes to the processes and practices of waste management throughout the industry. It is an aim of the present invention to overcome the difficulties that are arising from such changes.
The present invention provides a waste management facility for well installations, which integrates individual waste disposal commercial technologies and controls them by a bespoke control system. Although waste management systems are employed in the marine cruise liner industry and land based municipal waste industry, there are no such systems tailored to the needs of the well installation. The present invention allows for land, platform and ship-based systems, and provides a remedy to the increased difficulties that the industry is experiencing in controlling its pollution.
In accordance with the present invention there is provided an integrated waste management facility as set out in the accompanying claims.
The invention will now be described, by way of example, with refrence to the accompanying drawing, in which:-Figure 1 schematically shows an embodiment of a waste management facility in accordance with the present invention.
A hydrocarbon extraction well installation produces various waste sources shown at 1, including clinical waste, galley waste (i.e. food), paper, glass, metal and plastic, drilling sand (typically mixed with oily water), oily water, sanitary waste, black water' (from sewerage) and grey water' (from showers / washing). Waste sources may vary dependent on the specific installation.
The waste management facility makes use of various waste disposal processes 2 to cater for the waste sources. The facility as shown comprises: a) an autoclave for treating the clinical waste, b) a shredder for treating solid waste including paper, glass, metal and plastic, c) a cyclone separator for separating drilling sand from oily water residue, d) a sanitary waste unit for treating sanitary waste, e) a thermal destruction means for directly treating galley waste and treating outputs from other processes as described below, an oily water separator for separating the oily water, and g) a membrane bioreactor for treating black and grey water as well as output from the sanitary waste unit.
Outputs from the autoclave and shredder are fed, together with galley waste, to a destructive means for disposing of the waste. As shown, the destructive means enables thermal destruction of this waste. Sand separated by the cyclone separator is also fed to the thermal destructive means to destroy any remaining hydrocarbons. Oily water separated from the drilling sand by the cyclone separator is fed to an oily water separator, as is described below.
The thermal destruction equipment would be selected dependent on the type and quantity of waste stream on the installation. This destruction equipment can range from a simple marine incineration complying with the latest off-gas legislation, to plasma arc destruction, the latter being more energy intensive. The incineration would produce ash which could be used in civil construction dependent on the potential chemical hazard still present. The use of thermal destruction significantly reduces the volume of waste by approximately 98%. There is also the possibility of using the heat from the thermal destruction process for heating the installation and / or providing electrical power. Clean sand output from the thermal destruction equipment is returnable to the environment.
The oily water is separated by an oil / water separator, which are commercially available.
The oil produced by the separator is here fed to the thermal destructive means. The separated water is combined with other output waste as will be described below.
A sanitary waste unit is included for treating the sanitary waste. The output from the sanitary waste unit is fed, together with the black and grey water, to a cleaning means for remediation, which in this case comprises a membrane bio-reactor.
The membrane bio-reactor is a commercial piece of equipment which is used by the UK municipal water industry and is adapted if used on platform or ship-based systems. An aerated bio-reactor process promotes bacterial oxidation of the organic matter in the influent waste streams by developing an activated sludge ultimately producing carbon dioxide and water. The carbon dioxide vents from the bio-reactor with unused air from the aeration process, whilst the water generated passes through the porous membranes (0mm with micro film) as the permeate. The membrane acts as an effective barrier to the bacteria in activated sludge. Membrane fouling is minimised by creating a cross-flow across the membrane surface using the aeration process. The permeate from the membrane is suitable for re-use such as for laundry and toilet systems. The permeate line may include means for effecting further treatment processes such as UV sterilisation and / or an activated carbon filter, to help in reducing the levels of tanning. As mentioned above, the water separated by the oil / water separator may be combined with the permeate output from the bio-reactor. It is important that the permeate output from the bio-reactor complies with current legislation.
All equipment is controlled, managed and monitored using a fully interactive software control system which will act as the hub of the entire integrated waste management facility, allowing full control of waste loading profiles.
A platform, ship or land-based integrated waste management approach has benefits which include: -world-wide operation in an environmentally independent manner without legislative and public constraints, -reduction of waste management costs through the reduced manning for waste handling requirements, -reduction of the volume required for waste storage, -reduction of the frequency for the waste to be transported from the installation (hence reduced off load costs), and -improvements to health and safety conditions, whilst providing an output waste stream that is environmentally inert.
The major components are commercially available within the marine industry and have a commercial and military track record. This helps to ensure reliability of the facility.
The embodiment described above is exemplary only, and various alternatives / modifications will be possible within the scope of the claims.
